No cell signal? No problem. Turn your Smartphone into a satellite communicator with the SPOT Connect device.
Today’s smartphones provide a level of social connection far beyond what we imagined justa few years ago. But when you go beyond the reach of the grid your smartphone needs thehelp of SPOT Connect™ to keep you in touch with friends, family, and emergency personnel.Simply pair your smartphone with SPOT Connect, and get connected to a global satellite network that lets you send messages and GPS coordinates from virtually anywhere on the planet. Update Twitter and Facebook. Send text messages or a short email. Request non-emergency help from contacts or professional service providers. And in the case of a critical emergency, send an SOS
message requesting emergency assistance.

It actually lets you use satellites to send messages, so it's unrelated to your cellphone's normal voice or data connection. What you're asking specifically sounds like their "Type & Send" program, and you have to buy a preset number of messages (100 for $30 or 500 for $50).

Q:

i see that the specifications say that this device is compatible with Android 2.0 or later ... does this mean that it will not work with an iPhone?
